Once your card has been added to a mobile wallet, you can use your linked Save card by ‘tapping’ your mobile device near a payments terminal that accepts mobile wallet payments.
Apple and Android devices communicate using near-field communications (NFC). Samsung devices communicate both by NFC and over the card magstripe reader.
When using your mobile wallet, you will need to hold your mobile device near the payment terminal, your device will pick up the reader and will prompt you for the final approval to your purchase by requesting your fingerprint, password, or in some cases your pin number.
